Leaf-mine: Broad corridor overlying the midrib. The mine has a number of side branches that distally widen strongly, and may coalesce. Primary and secondary feeding lines very conspicuous (Bladmineerders van Europa). Pupation external, in soil.

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall. The larvae lie on their sides within the mine and use their pick-like mouthparts to feed on plant tissue.

Posterior spiracles with three elongated Bulbs (Bladmineerders van Europa).

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Yellow; anterior spiracle openings arranged in large arcs, not elevated on a fan-like structure; posterior spiracles each with a central opening larger and more raised than the lateral openings (White, 1988).

Comments: Uffen in Chandler (1978)did not indicate whether his host records are British or Foreign and are therefore tentatively included under 'Hosts in Britain' and 'Hosts elsewhere'.
